CN201844322U - LED (light emitting diode) street lamp - Google Patents

Abstract

The utility model discloses an LED (light emitting diode) street lamp comprising a lamp shade, a lamp body and LED lamps arranged on the lamp body, wherein the LED lamps has a module structure with series connection crossed with parallel connection; in addition, the light emitting zones of the LED lamps form a rectangular shape; and the lamp shade and the lamp body are fixed together. The LED lamps has the module structure with series connection crossed with parallel connection, therefore, even through one LED lamp is in failure, the illuminating effect of the whole street lamp is not influenced and the service life of the street lamp is indirectly prolonged; the modularized LED lamps are easy to replace, therefore, the convenience for the maintenance and the repair of the LED lamps is greatly enhanced; and he lamp body has a plastic structure with silver air jetting, therefore, the weight of the street lamp can be greatly reduced to a great degree and the manufacturing cost of the street lamp is lowered.

Description

A kind of LED street lamp

Technical field

The utility model relates to a kind of LED street lamp, belongs to lighting field.

Background technology

Light-emittingdiode (English: Light-Emitting Diode, be called for short LED) be a kind of semiconductor element.At the beginning indicator lamp, display boards etc. of being used as more; Along with the appearance of white light emitting diode, also be used as illumination.

It is the new type light source of 21 century, has long, conventional light source such as the cracky advantage that can't compare with it not of efficient height, life-span.When adding forward voltage, the light-emitting diodes physical efficiency is sent monochrome, discontinuous light, and this is a kind of of electroluminescent effect.Change the chemical composition of the semi-conducting material that is adopted, can make light-emittingdiode be emitted near ultraviolet ray, visible light or ultrared light.

Because LED operating voltage low (only 1.5-3V), can active illuminating and certain brightness is arranged, brightness can use voltage (or electric current) to regulate again, itself is shock-resistant again, anti-vibration, life-span are long, therefore played increasing application in the demonstration field, especially utilize in the street lamp field, have brightness height, long technological merit of life-span.

But, because street lamp is in the environment of wind and weather for a long time, be easy to break down, therefore, produced certain obstacle for promoting the use of of LED street lamp.

The utility model content

The utility model provides a kind of long service life, changes the simple LED street lamp at the high shortcoming of transitional street lamps fault rate, and this street lamp has technological merit preferably.

The utility model solves the problems of the technologies described above the technical scheme that adopted as following description:

A kind of LED street lamp comprises lampshade, lamp body and is arranged on LED lamp on the lamp body that described LED lamp is the modular structure that series, parallel intersects, and the bright dipping zone of above-mentioned LED lamp forms a rectangular shape, and described lampshade and lamp body are fixed together.

Further, preferred construction is that the termination of described lamp body is the jet plastic construction of silver color.

Further, preferred construction is that described LED lamp module is set to a plurality of, and is evenly distributed on above the lamp body.

The utility model taked the beneficial effect that technique scheme had such as below description:

The first, because above-mentioned LED lamp is the modular structure that series, parallel intersects, therefore, even a LED lamp breaks down, does not influence the illuminating effect of whole street lamp yet, thereby prolonged the service life of street lamp indirectly;

The second, because Modular LED lamp ratio is easier to change, therefore, also strengthened the maintenance and repair of LED street lamp greatly;

The 3rd, because lamp body is the jet plastic construction of silver color, therefore, can alleviates the weight of street lamp to a great extent, and reduce the manufacturing cost of street lamp.

Description of drawings

By coming that below in conjunction with accompanying drawing the utility model is carried out further detailed description, above-mentioned advantage of the present utility model and technique effect will become more obvious.

Fig. 1 is the structural representation of the utility model LED street lamp.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail.

As shown in Figure 1, described LED street lamp comprises lampshade (not shown), lamp body 1 and is arranged on LED lamp 3 on the lamp body, the modular structure that described LED lamp 3 intersects for series, parallel, the bright dipping zone of above-mentioned LED lamp forms a rectangular shape 4, and described lampshade and lamp body 1 are fixed together.

In addition, the zone of described LED lamp rectangular shape 4 is set to a plurality of, in the embodiment in figure 1, is two identical rectangular areas, and, on the lamp body between the rectangular area 1, also have some apertures 2.

Preferred version is that described LED lamp 3 uses seven strings four integration module mode also, has promptly guaranteed single 1W

LED has the characteristic of higher light efficiency, makes assembling simultaneously again and produces the convenience very that becomes.

Simultaneously, because above-mentioned LED lamp 3 has formed a rectangular area, therefore, its optics uniformity is higher, and its main implementation is to adopt single LEDs to carry out the secondary light-distribution mode separately, makes the hot spot of street lamp become a good rectangular area, usually, adopt design like this, the uniformity of LED street lamp light is greater than more than 0.5.

In addition, because LED street lamp 3 is taked modular mode, simultaneously, its corresponding street lamp heat radiator adopts modular mode, makes the processing of radiator and follow-up assembly become comparatively convenient.

Among the preferred scheme, the plastic construction that the termination of described lamp body 1 adopts silver color to spray paint has alleviated the overall weight of street lamp preferably, has better technical effect.

It should be noted that; above-mentioned specific embodiment is exemplary; under above-mentioned instruction of the present utility model, those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improvement or distortion drop in the protection domain of the present utility model.

It will be understood by those skilled in the art that top specific descriptions just in order to explain the purpose of this utility model, are not to be used to limit the utility model.Protection domain of the present utility model is limited by claim and equivalent thereof.

Claims (3)

1. LED street lamp comprises lampshade, lamp body and is arranged on LED lamp on the lamp body, it is characterized in that, described LED lamp is the modular structure that series, parallel intersects, and the bright dipping zone of above-mentioned LED lamp forms a rectangular shape, and described lampshade and lamp body are fixed together.

2. LED street lamp according to claim 1, the termination of described lamp body are the jet plastic construction of silver color.

3. LED street lamp according to claim 1 and 2, described LED lamp module is set to a plurality of, and is evenly distributed on above the lamp body.
